New York Attorney General Eliot Spitzer on Thursday sued Internet marketer Intermix Media Inc., claiming the company installed "spyware" and "adware" that secretly install pop-up ads on screens that can slow and crash personal computers, the Associated Press reported.

Spitzer said the suit filed in New York City against L.A.-based Intermix Media moves against the redirecting of computer users to unwanted Web sites that include ads, the adding of toolbar items and the delivery of ads that pop up on computer screens. After a six-month investigation, Spitzer concluded the company installed a wide range of advertising software on many personal computers nationwide.

Spitzer's civil suit accuses Intermix of violating state General Business Law provisions against false advertising and deceptive business practices. He also accuses them of trespass under New York common law.
